What if the sun became a black hole?

Answer 1

We would all die. There would be no sun, no light, so all the plants would die, so animals would die, we would have no food and starve. Solar power would not be available. We would not be pulled in and would continue to orbit as the mass would remain the same.

Answer 2

Our sun will never turn into a black hole. It is a lower-mass star. Only some higher-mass stars turn into black holes.

That said, if the sun were replaced by a black hole, the effect on Earth's orbit would depend on the black hole's mass. If it were a 1 solar mass black hole, then Earth's orbit would not be affected. If it were a more massive black hole and the replacement were sudden, Earth would enter a more elliptical orbit with a smaller periapsis what it currently has.

Answer 3

If the sun became a black hole, it would have the same mass but be collapsed to a much smaller size. Its gravitational pull would be much stronger, but since it's so far away, the effects on Earth would be minimal, mainly just losing the light and heat energy.

Answer 4

We would all die. even if the earth didn't get pulled in by the gravity, no light or heat from the sun would destroy all life on the planet.

Answer 5

Assuming the mass stayed the same, all the planets would orbit the new black hole. However, all life on Earth would die without the energy of the Sun.

Answer 6

The sun is not massive enough to collapse upon itself to become a black hole, near the end of its life it would merely expand and engulf the terrestrial planets.

Answer 7

Nothing much would happen, except all life on earth would die because no heat or sunlight for plants or life to survive.
